1. Spanish SMS 71-160 chars not sent. This was because calculateLength
allowed for single-segment EMS encoding, while encodeUserDataPayload
did not. For now, change calculateLength to match encodeUserDataPayload
(ie, fallback to UTF16 in this case). (b/2224849)
2. Unicode value of N w/tilde was incorrect. (b/2224849)
3. Add '\' and '/' to the list of valid separators in CDMA SMS numeric
addresses. (b/2236527)

Changes the semantics of SmsHeader from containing only opaque data
to exposing occurs-once frequently-used fields together with a list
of opaque fields. Also changes the coding to and from byte array to
be symmetrical, whereas previous encoding had an extra length field.
Cdma SmsMessage -- cleanup of code paths along with adjustments to
match the new header semantics, which should address at least some
of the issues with concatenated messages. See http://b/issue?id=1809759
